Saturday Night Live has booked a couple of living entertainment legends for its Christmas show this year. TVLine reports that Martin Short will be hosting the December 15th episode, with Sir Paul McCartney serving as musical guest. Jamie Foxx and Ne-Yo were previously announced as the host/musical guest for the next new episode, which airs December 8th. This will be Martin Short’s third time hosting the show (his last was in 1996) and Paul McCartney’s fourth stint as musical guest (his last was in 2010). Short, as SNL buffs recall, was a cast member for the 1984-1985 season. If the writers don’t make him reprise his role as Jack Frost from the Tim Allen vehicle The Santa Clause 3: The Escape Clause, it’ll be a major missed opportunity.
